A community space in the heart of central London has been completely transformed and by 6a architects. The new building, incorporating an old basement gymnasium, is home to Holborn Community Association, has a 100-year history which has been sensitively referenced in artwork created by artist Caragh Thuring on the façade of the building. What was solely an old basement gymnasium has been rebuilt as a light-filled, naturally ventilated, low energy space, extending upwards with two new public-facing floors. 6a architects specified Junckers solid Oak Harmony Driftwood Grey two-strip flooring, a pale shade of grey. Suitable for multi-purpose use, the sprung floor fitted in the gym as well as in the club rooms, will enable the community centre to maximise earnings through hires, being able to offer a safe space for everything from various sports to arts and social events. Said Stephanie Macdonald of 6a architects: “The floor looks fantastic and really unusual, a beautiful warmth of timber and colour for the gym and the clubrooms which is going to allow them to be used equally well for hires and events - a really beautiful set of spaces for community use”. Throughout the building, an emphasis on pale, light-reflecting colours and materials minimises reliance on artificial lighting. The light-coloured Junckers Driftwood Grey Oak provides the centre with a durable floor which helps maximise natural light levels. It can be sanded and refinished up to ten times without loss of performance and will serve the centre well for 60 years plus. Junckers floors carry the Danish Indoor Climate Label, which is recognised by BREEAM. Having undergone extensive degassing and odour testing to ensure there are no harmful chemicals, a Junckers floor will help maintain a healthy indoor climate. Stirling Prize nominated 6a architects worked closely with Thuring whose artwork features throughout the architecture. For the etched glass façade which runs the width and height of the building Thuring drew on stories from the community and local area which are inscribed onto the glass alongside irregular mortar lines of the original brickwork. For the gymnasium, Thuring created a bespoke woven fabric, echoing the brickwork motif of the façade, which lines the acoustics panels on the upper walls. The flooring contractor was Junckers Approved Contractor Hutchison Flooring. 

Walsall Council is undertaking a major redevelopment plan to re-imagine parts of the town. Gallery Square, the home of the area’s brand new art gallery, is the first space to be updated under the plans. WoodBlocX Landscaping was commissioned by Acadis UK to supply the street furniture for this part of the project.Gallery Square is a large open space, the designers have used colour in the form of a series of large squares, of differing sizes, painted on the floor to create interest from the ground up. The design and layout of street furniture aims to provide plenty of space within the square for visitors to the gallery and the wider public to use, it also allows for adequate social distancing as and when required.For this project we took the proposed design and recreated it using our versatile modular system. Our team is able to take the technical detail from drawings and create full and detailed design proposals using our bespoke software. Once the plans were finalised, we supplied a series of large seating solutions that were installed by the contractors in March 2021.

The new HMRC regional hub at the Arena Central complex in Birmingham has provided over 240,000 sqft of grade A commercial space over its ground and 13 upper floors. The building features an external envelope of geometric glass and aluminium facades that create an iconic feature to this area of central Birmingham. Working closely with the façade contractor NACWL, specialist architectural metal fabricator Metalline have manufactured and supplied over 9000 m2 of aluminium Unity Rainscreen Panels from their recently extended facility in Cannock. Delivery which commenced in September was completed within 10 weeks. The specification also included over 5000 m2 of Ultima Insulated Spandrel panels along with soffits, column casings and transition panels. The detailed design of the building’s façade demanded a uniformity of colours which was achieved using a single ingot of J57S Up aluminium. The Ultima Insulated Spandrel Panels were finished in a black polyester powder coating. The individual Unity rainscreen panels were supplied in a two – tone specialist 1934 and 1953 Unatex silver anodised finish.

Working in close co-operation with the building envelope and façade contractor Colorminium, Metalline have produced a range of bespoke 3D twisted fins that will when complete take centre stage on the exterior of the redeveloped Minories Hotel in the City of London. This stunning feature was the brainchild of ACME architects who in collaboration with The Murphy Façade studio have designed a series of full storey aluminium fins that clad the existing precast frame and create a bridge between that and the unitised glazing. Fabricated offsite at Metalline’s state of the art manufacturing facility in Cannock, these 42 metre height fins were produced in 3.5 metre lengths with a depth of over 800mm. Manufactured in 2 parts, each element was assembled using a combination of aluminium stud welding and bonding techniques developed by Metalline. The fins were then fitted to the glazed panels using an aluminium bracket support system to ensure structural integrity. Finished in dark and light bronze PPC to mimic an anodised effect, the fins will create shading for the hotel’s occupants as well as an iconic architectural vista for this stand out landmark project.

Unit 25 Cambridge Science Park is a state of the art facility providing laboratories and office space for Bio tech and Med Tech companies. This BREEAM Good facility was built by SDC and features an external façade of glass, metallic panels and fins for solar shading. At each corner of the building a chamfered picture frame feature of curtain walling and panels, adds to the modern design. Metalline who manufacture a range of architectural fabrications worked closely with MTW Architectural the specialist façade contractor to ensure that all materials were delivered on time and to exact specification. They supplied in excess of 1000m2 of A2 Ultima insulated panels, Unity interlocking rainscreen panels, interlocking soffits, copings, pressings and cills for the project.The picture frame finish to the corners of the building were finished in a slate grey polyester powder coating. The horizontal rainscreen panels used to break up the expanse of glass shown on the front of the building were finished in tiger drylac 068/70764 PPC This finish mimics an anodised finish and features on all four sides of the building

This state-of-the-art office building located in the heart of the City of London is the new European headquarters for an international financial organisation.The 10-storey office building was the largest commercial fitout in 2019, housing up to 6000 members of staff with more than one million square feet of space. This modern building is truly unique and offers employees a range of facilities not usually seen in most office developments. Located within the building is an auditorium and conference centre, a health centre, a nursery and playcentre, a fully equipped gym, therapy rooms for sports massage and acupuncture, contemplation and resting rooms. As part of the project build multiple entrances needed to be secured, including the main reception, a gym and childcare centre, a cycle parking entrance and a contractors entrance. The client specified early in the project that all entrance solutions needed to be integrated with a contactless biometric readers, to ensure a high level of authentication. Whilst preventing unauthorised access to the building was crucial, the solution needed to complement the architectural intent and provide the smooth flow of authorised users passing through the prestigious building.

US aircraft manufacturer, Boeing, officially opened its first European manufacturing site in Sheffield in 2020. The £40m plant, covers 6,200m² and is responsible for making actuation system components for the 737 and 767 aircraft from raw materials sourced in the UK.The site, designed by D5 architects and installed by the main contractor J F Finnegan, followed the brief of functional adaptability, employee wellbeing and sustainability.Marshalls’ hard landscaping products were used for the forecourt, pathways and surrounding carpark to the building. Modal in Textured Mid Grey Granite paved around the entranceway and paths, while Modal Priora in Anthracite was used in some detailed areas. For the car parking spaces, Keyblok Priora in Natural was used alongside Charcoal to help define parking spaces and illustrate car charging and disabled bays.The use of Priora permeable paving supports the sustainable drainage for this project, the patented nib on the edge of the blocks creates voids through which water falls into a specially prepared sub-base, making this project free of surface water for years to come.

Canal Architectural were approached to design, manufacture and install a luxury feature staircase for Gresham Street. A leading workspace design company collaborated with the Technical Sales Team to engineer a four flight staircase for the atrium of the building.The 50,000 sq ft of commercial space in the heart of London was developed to connect its employees and working spaces together. The mild steel structure featured oak timber box treads, painted stringers, bronze metallic balustrade and a wrapped brown leather handrail. The entire development was transformed into a contemporary co-working area for a modern and innovative space for the specialist investment firm.The Canal site team worked closely with the contractor throughout the entire installation process to ensure smooth delivery in line with current building regulations. Canal Architectural are proud to have a long-standing collaborative relationship with leading design and build firm. Canal has worked directly with the workspace design company to engineer exquisite architectural metalwork designs for some of the UK’s most prestigious projects over the years including Gresham Street.

Apex Heritage Cast Iron rainwater system from leading specialist Alumasc was commissioned as part of the £800 million extension and restoration of St Pancras International, London.The extension and interior of the station comprised all the modern facilities expected in Britain’s most advanced station, however, work on the oldest Grade 1 listed part of the station called for the faithful and painstaking restoration of the gothic red brick façade, to retain the original detail of George Gilbert Scott’s design.Existing rainwater systems, despite being almost 150 years old, were still in use. As part of the redevelopment project English Heritage insisted that any new rainwater details must faithfully reproduce the original patterns of the Victorian rainwater goods used when the station was first built. Alumasc worked closely with the main contractors to produce bespoke moulds, creating cast iron replicas of all the existing pipes and hoppers to take away rainwater from the vast single span roof, which is still the largest of its type in the world.

The Audley Stanbridge Earls retirement village is an exclusive residential development of 155 luxury retirement apartments and cottages designed around a Grade II listed Tudor Manor house on a 32 acre site near Romsey, in Hampshire. Underfloor Heating had been specified as part of the design and the large floor areas now needed to be finished with floor screed that could be installed quickly and efficiently within the operating windows provided by the main contractor.TOPFLOW Screed A Thermio + offers a higher thermal conductivity than conventional sand-cement screeds, can be laid thinner and fully encapsulates heating pipes without leaving any voids. This makes it ideal for use with underfloor heating systems where it helps to improve the thermal performance and energy efficiency of buildings. All TOPFLOW Screed A products are made from gypsum and are completely cement free, with a binder made from 98% recycled material. This gives it a lower carbon footprint than a conventional cement-based screeds, saving up to 20.45kg CO2e per m2, making it a more sustainable choice.

A private landowner wanted to develop a large multi-purpose agricultural facility for both arable and potential livestock use at their farm in Leicestershire. Part of the requirement was external surfacing, which would need to be hard wearing and deliver long lasting durability in this demanding environment, including regular use by heavy agricultural vehicles. After discussions with the contractor, the solution proposed was Tarmac’s TOPFORCE fibre reinforced concrete with a combination of synthetic macro and micro fibres. TOPFORCE is a fibre reinforced, high performance concrete, that eliminates the need for some traditional reinforcement. Quicker and easier to place than traditional steel mesh reinforced concrete, TOPFORCE concrete offers excellent long-term durability and performance. This makes it ideal for heavy duty flooring or hardstanding applications. This solution would deliver a saving in both labour and material costs and avoid the budget impact of the rising cost of steel. As well as improving the durability off the finished concrete, the use of macro fibres would also improve sustainability significantly by reducing embodied carbon compared to traditional steel reinforcement. 

A Gloucestershire based independent care provider has recently completed a 46 bed extension on their care home for clients with dementia and nursing care requirements. Having worked with the contractor on a similar project, Astor Bannerman were recommended to the company to supply ceiling track hoists in an effort to future proof the needs of the home. With floor space at a premium, the company wanted to move away from the traditional style mobile hoists, which need to be stored away when not in use. Also, as using a ceiling hoist system normally only requires one carer to operate, this enables the company to adapt to the possible implications of Brexit on staffing levels.During the installation, we successfully added an XY (H-frame) hoist system into 3 assisted bathrooms and added 3m straight track OT200 hoists in 6 bedrooms allowing simple transfer in an out of bed.Fixings were also installed during the main build in the remaining 40 bedrooms, enabling the care provider to retrofit track and hoists as and when they require them at any point in the future.

McMillan House is a first class development providing luxury rental apartments to young professions in the local area of KT4. Built in 1950 it had been used as an office building for over 50 years. Now delicately restored, McMillan House will provide 46 luxury 1, 2 and 3 bedroom rental apartments upgraded to the highest standards.After the main contractor won the project, we were requested to propose an acoustic solution that would comply with Building Regulations. As part of this 2,115m2 luxury conversion, the Soundis dryscreed board with a resilient layer of wood fibre was selected, this is a high quality, interlocking dry floor screed system using gypsum fibreboard technology.This system, was selected due to its high thermal conductivity allowing for the use of the proposed underfloor heating systems throughout the flats, but also for its main purpose of Meeting Regulations, where it’s incorporated Wood Fibre Resilient Layer effectively reduces impact sound transmission from footfall. As traffic can be taken immediately once the glue had hardened, on the low installation thickness acoustic board.

Valentines house, an 11,000m2 building in Ilford. Originally a commercial office block, it’s position adjacent to both Crossrail and TFL red routes meant it was a prime candidate for conversion to desirable one and two bedroom apartments.The refurbishment works consisted of extending 4 stories including structural strengthening and new envelope to incorporate full fit-out of 122 residential units and 3 retail areas.As part of the conversion, main contractor John Paul Construction, required the expert installation of around 10,000 m2 of acoustic flooring to achieve Approved Document E Building regulations. As part of the acoustic flooring package, Soundis value engineering option of Soundis 10mm Acoustic Cradles, Base Pads, Riser Stackers and 18mm P5 T&G chipboard was selected. Our Cradle and Risers are manufactured from 100% recycled materials assisting to the sustainability targets of projects. An acoustic cradle and batten system was chosen, to level out floor imperfections and to minimise impact noise from passing footfall. Airborne wasn’t so much of a concern in this build due to the high mass concrete subfloor.

A £5m renovation scheme in Warrington has been presented with the “Best Change of Use to Existing Building” regional award by LABC (Local Authority Building Control) and Warrington Borough Council.The scheme required the conversion of a former office building, Kings Court, in Central Warrington, into 32 luxury flats, comprising of a mix of one and two bedroom apartments, arranged over three floors of accommodation. These flats are situated above retail units and restaurants. The renovation included a further two exclusive duplex penthouses for Phase 2.As part of the renovation, Main Contractor Emerald Bay Construction required an acoustic flooring solution to meet Approved Document ‘E’ Building Regulations and therefore provide overall resident comfort, in terms of Sound Insulation between separating floors. As the building structural floor was primarily concrete, Soundis put forward a solution that involved 2,072 m2 of Soundis ChipPanel 28 to help with Impact Noise. This shallow deck floating floor is ideal for concrete floors where Airborne Noise is not an issue but Impact Noise Attenuation needs to exceed the requirements of current Building Regulations.

Work was undertaken at Ringside House in order to convert the building from offices into 46 luxury one and two bedroom apartments.Acoustics are vital for maintaining comfort in private residences, particularly in multi-level apartment buildings with numerous occupants, due to the noise being passed between floors and walls.Soundis along with our installation partner UK Acoustic Systems were brought in by the main contractor PDR Construction to provide 2,862m2 of acoustic flooring. After site visits, we agreed to use one of our Soundis Cradle & Batten Systems, as this system provides excellent impact and airborne noise reduction capabilities, can be used to level out uneven floors, creates an underfloor void for utilities such as piping/ wiring and even underfloor heating. Our Cradle and Risers are manufactured from 100% recycled materials assisting to the sustainability targets of projects. After the project completion, we successfully achieved our goal of providing an excellent flooring solution, which could create a peaceful environment and improve the acoustics within the building, helping add value to the luxury apartments.

The historic Aberdeen Music Hall has been restored and redeveloped by Architects BDP. The Category A listed concert hall has been completely refurbished and now includes a performance studio, creative learning space and a café/bar. Nearly 1,500m2 of Junckers solid Nordic Beech Classic flooring has been fitted as part of the transformation, including in the impressive 1,300 seat auditorium, which now has step-free access to all levels. Nordic Beech with its white pigmented finish offers a light and bright backdrop to the interior and makes the most of the architects’ new architectural lighting by reflecting an abundance of light. By specifying the same floor for much of the building, the various spaces are seamlessly connected by a unifying element. At 140mm wide, Junckers’ signature wide board, long-length floor boards really come into their own in the open spaces and circulation routes, offering a clean and elegant look. Solid beech is amongst the most hard-wearing timbers used for flooring and Junckers’ pre-finished floors are well-known for their durability. The flooring contractor was West End Flooring. 

The Friedrichscarrée is a modern office and retail complex in the center of Stuttgart.Named after the former king of Württemberg, Friedrich I., it is characterised by its modern architecture and glass front. In addition to numerous companies, it now also hosts retail, catering businesses and event spaces. The good access to public transportation and the close proximity to restaurants and cultural institutions, make Friedrichscarrée an attractive location for businesses and visitors.As the general contractor for the expansion, Lindner carried out an extensive interior construction - ranging from drywall work to floor systems and wall cladding. In addition to high-quality floor coverings and also partly automated partition walls, the special construction of the hollow floor FLOOR and more® for the pedestal in the barista bar was a central element of the revitalisation. Lindner hallway ceilings LMD, heating and cooling ceilings and acoustic sails were also installed to optimise room acoustics.Furthermore, GiB mbH supported Lindner in upgrading the existing fire protection. The entire conversion was carried out during ongoing business, which required precisescheduling of noise-intensive work.

Hospital Specifies TITAN Lite™ 120:60 From FIREFLY™An 18-month contract being carried out by a leading UK fire contractor has involved installing large quantities of the TITAN Lite™ 120:60, manufactured by TBA FIREFLY™, to create fire barriers above ceiling voids throughout many parts of the hospital.The hospital has 660 beds and provides medical and surgical care to a third of a million people with the building dating back to before the beginning of the Second World War. The refurbishment work, concluded at the end of November 2021, was being carried out by Plymouth based Ventro Ltd. whose operatives have had to work in many areas during the evenings and weekends in order to avoid disruption to the hospital’s everyday activities, including the treatment of patients.Following early appraisals of the fire protection requirements within the ageing property and taking into account the large quantities of different mechanical services to be accommodated into the upgrades, the hospital’s estates department decided to raise the specification for the work from 30 minutes integrity rating to a full two hours. The Site Agent for Ventro, John Roberts, commented: “As a specialist fire contractor working across the whole of the UK and beyond, we have employed FIREFLY™ products on many projects over the years and expect to continue doing so. In the early stages of this contract, which began on site in May 2020, it was thought APOLLO Lite™ 30 minutes would be appropriate, but the hospital then switched this to TITAN Lite™ 120:60. We have been installing the TITAN Lite™ in many parts of the hospital, including most recently in the ceiling voids over the kitchens. This has been done by fixing metal angles across the soffits and then using the special tape and staples to secure the fabric to it. Despite the large number of services making the number of penetrations to be deal with quite challenging, our teams find the FIREFLY™ relatively easy to install.”FIREFLY™ TITAN Lite™ 120:60 has been developed as a flexible fire barrier to provide compartmentation of larger concealed spaces within different types of buildings including factories, warehouses and railway stations.By offering 120 minutes integrity and 60 minutes insulation, TITAN Lite™ 120:60 exceeds the minimum requirements relating to Fire Barriers as detailed in the UK Building Regulations: Approved Document B (Fire Safety). Firefly is manufactured using specially treated woven glass fibre fabrics. 

Project: Creative Centre, York St John UniversityClient: Tate+Co ArchitectsScope of project: Design and supply 24 bespoke-sized rooflights for the roof of a triple-height atrium to fit within apertures in a glulam timber grid.Products: 24 bespoke sized em.glaze rooflights, some with concealed actuator smoke ventsThe ChallengeThe roof of the striking 14m, triple-height atrium, which forms the centrepiece of the newly opened Creative Centre at York St John University, features a glulam timber roof grid. Architects Tate+Co wanted to punctuate that grid with bespoke sized rooflights to bring even more light into a space which is used as an exhibition, teaching and theatre space, as well as somewhere for students to mix and relax. The rooflights had to have a sleek, minimalist aesthetic, in line with the overall design intent of the atrium and, because almost all the services in the atrium are hidden, needed to be available with matching concealed actuator smoke vents.The SolutionWhitesales designed and supplied 24 bespoke-sized em.glaze rooflights which suited the specification perfectly. The flush-glazed glass-to-edge design of the em.glaze units with flat sealed glass units fitted within a fully welded, thermally broken aluminium frame achieved the lean, crisp look the architects were looking for. The fact that they were also available with fully concealed actuators in the smoke vents supplied by our affiliate business Sertus was an added bonus. All the rooflights were supplied for the project complete with preformed 300mm PVC splayed upstands, which enabled them to be fitted directly into the glulam grid, saving the contractors time on site. They were also fitted with specially coated glazing which allowed for a degree of solar gain and contributing to the low energy requirements of the BREEAM Excellent rated building.‍The BenefitsAs well as the meeting the design specification, Whitesales’ technical team helped to ensure that the em.glaze rooflights could be installed quickly and efficiently by the main contractors Kier Construction. We estimate that our recommendation to supply the units with preformed 300mm PVC splayed upstands saved the roofing team at least two weeks on site because they didn’t have to construct the upstands themselves and the integrated splay made waterproofing the roof a lot easier. Tate+Co Director Andy Baker-Falkner is delighted with the em.glaze units: “We liked the lean, crisp design of the Whitesales em.glaze units, particularly with the clean white reveal and option for fully concealed vent actuators.”

CHALLENGEWestfield, the world’s largest listed retail property company, is set to change the face of retail in the United Kingdom with the opening of its new flagship development – “Westfield London” – at White City, London.Beneath a spectacular, undulating glass roof, the £1.6 billion Westfield London destination combines over 150,000m2 of retail, restaurants, cafes, bars and leisure facilities to create the ultimate shopping and leisure destination.Westfield London will act as a catalyst for the redevelopment and regeneration of the wider White City area with a further £1billion investment expected in the immediate vicinity over the next 10 years.SOLUTIONKnauf Insulation supplied Rocksilk® RainScreen Slab as part of the rainscreen cladding system to the external stone clad façades of the development and internal stone clad stairwell and elevator areas. The specification of Rocksilk® RainScreen Slab provided both performance and installation benefits to both client and specialist installing contractor.Rock Mineral Wool has a Euroclass A1 reaction to fire classification to BS EN ISO 13501- 1, the highest classification available. With rainscreen cladding incorporated into building design fire performance is particularly important and, as such, a non-combustible component such as Rock Mineral Wool provides the ideal prevention against the spread of fire. The non-combustible nature of rock mineral wool ensures that it will not burn, will not give off toxic smoke and will not suddenly ignite in a fire due to ‘flashover’.Another key specification element related to the speed and ease of installation. The required thermal performance of the building was dependent on the correct installation of the specified insulation product. Rocksilk® RainScreen Slabs are easy to install down to their superior workability ensuring installation stayed within the tight time constraints. Rocksilk® RainScreen Slab is treated with a water repellent additive to ensure the building structure is protected against rain penetration and it can also be installed with either face adjacent to the sub structure.Rocksilk® RainScreen Slab provides an additional benefit for the installing contractor as it is designed to adapt to minor imperfections in the building’s substructure. The rock mineral wool product ‘knits’ together, ensuring intimate contact between slabs ensuring all joints are closed and thermal efficiency is maximised.Rocksilk® RainScreen Slab has excellent acoustic properties, which contributed towards the acoustic performance of the structure in order to comply with both sound insulation and sound absorption requirements.What’s more, individual packs of Rocksilk® RainScreen Slabs are compression packed together in Knauf Insulation’s innovative packaging method, Supakube. The advanced compression technology and strong packaging materials ensure the product is easy to transport and store, reducing environmental impact and causing minimal disruption on site and the surrounding area.

Salamander Street is a mid-market rent initiative that provides high quality affordable homes in the heart of Leith, Edinburgh. It comprises 199 flats and maisonettes across six storeys of accommodation, constructed over a basement car park.It was designed by 7N Architects, which specified Knauf Insulation’s 50mm Rocksilk® RainScreen Slab to insulate the ventilated façade. They chose this product because it met the brief’s two critical performance factors: thermal performance and fire safety.It is a Rock Mineral Wool insulation slab with a thermal conductivity of 0.034W/mK, so it delivers the required U-value of 0.16 W/m2K. It is non-combustible with the best possible Euroclass A1 reaction to fire classification and is BBA certified for use in a wide range of build-ups in high rise buildings. This means it complies with Building Regulations in Scotland that restrict the use of combustible materials on most buildings over 11m.The Salamander Street development was overseen by main contractor Cruden Building East with sub-contractor Soundtex responsible for installing the insulation.It was constructed using an Ancon Brick Restraint System. Ancon has undertaken independent third-party tests to demonstrate that its restraint system does not require a compression sleeve when used in conjunction with Rocksilk® RainScreen Slab under 180mm thick. This provided a huge saving in labour costs for Soundtex as fasteners are usually inserted into compression sleeves by hand.Throughout the build, Knauf Insulation’s Specification Team attended regular project meetings and conducted site visits to check the quality and progress of installation. Rocksilk® RainScreen Slab is optimised for ease of installation and improved robustness, making it easy to manoeuvre into position. At Salamander Street, the Specification Team noted the uniformity of installation and perfectly staggered joints. This is important because it ensures there are no gaps, which could reduce thermal and acoustic performance – a common issue with rigid foam board insulation.Rocksilk® RainScreen Slab is manufactured with ECOSE® Technology, Knauf Insulation's unique bio-based binder that contains no added formaldehyde or phenol. It is made from natural raw materials that are rapidly renewable and is 70% less energy-intensive to manufacture than traditional binders, so it is more environmentally friendly.Products made with ECOSE® Technology are soft to touch and easy to handle. They generate low levels of dust and VOCs and have been awarded the Eurofins Gold Certificate for Indoor Air Comfort.The Rocksilk® RainScreen Slab insulation was installed in conjunction with Knauf Windliner sheathing board for maximum performance.Thanks to Knauf Insulation, the residents of Salamander Street will enjoy warm, cosy homes that meet the highest standards of fire safety.

DAYLIGHTING TAKES OFF AT HEATHROWThe ageing glass skylights of Terminal 4 at London’s Heathrow Airport were in need of repair. The challenges for the project’s main contractor was finding a way to keep the project moving with little disruption to this busy terminal and also maintaining the airport’s security protocol.The answer was a single-source solution presented by Structura UK, the curtainwall engineers who are the exclusive distributor of Kalwall products in the United Kingdom and Ireland.18,836 square feet (1750 square meters) of Kalwall Skyroof® cladding were used above the terminal’s International Departure Lounge and check-in desks to replace the 30+ year old glass skylights. The Kalwall translucent sandwich panels are fully Aviation Security in Airport Development (ASAID) compliant with regards to blast performance and improve the solar control and insulation for the space below. In fact, Kalwall 100™ panels were specifically chosen to exceed code requirements, therefore future-proofing the project.The whole retrofit was completed externally using a custom moving scaffold and during evening hours, meaning there was no disruption to the inside of the building. And, as far as value, the lightweight translucent panels allowed for the existing substrate to be adapted and reused – a savings of nearly $9 million (£7m) in project costs and more than a year off the build timeline.“Structura UK was a new supplier to the major capital projects programme on the Airport (and) they delivered a flawless installation despite multiple challenging circumstances including adverse unseasonal weather, unexpected contaminated materials and multiple design changes,” says Ben Hooper, Senior Project Manager at Heathrow.Structura worked in conjunction with Structural Engineers Webb Yates for a scheme designed by Pascall+Watson architects. The project proved so successful that main contractor Balfour Beatty named Structura as their ‘Most Promising New Supplier 2018’. Kalwall offers complete line-of-sight protection, maintaining privacy for the security screening area and departure lounges while bathing the interior with diffused daylighting, regardless of the weather. Apart from providing the visual protection, its inherent strength and heavy-duty impact resistance make it ideal for secure locations such as this. It offers the highest protection in terms of windbornedebris and resistance to impact, abrasion and point loads. Not only is it man safe, but Kalwall achieves S:AA (BS 476 part 3) and Broof(t4) to EN 13501 part 5 for external fire performance.The exterior face is colour stable and includes a UV resistant, self-cleaning surface. This means that normal rainfall helps to keep the surface free of dust and dirt while at the same time retaining its original colour during the weathering process.

Fire resistant, multi-directional, high movement, structural joint sealing of floor slabs from below for 120minutes, EI Fire ratings using Emshield-DFR from NCC Movement joints Limited.St William is a division of Berkely Homes, predominantly working on some of the most technically complex regeneration projects on brownfield sites, at the heart of communities across London, and typically with a landscape-led approach. Riverside Park and Gardens is being developed on the former Leven Road Gasworks in Poplar, East London, forming part of the 20 acres Aberfeldy Village scheme. This is an ambitious regeneration project in the borough of Tower Hamlets, with around 3000 new homes, plus shops, offices, cafes, bars, and a cinema, as well as extensive landscaped gardens, play areas, and riverside walks.On this important development by the River Thames, the structural floor slab joints ranged from only 15mm to 25mm wide, but they were subject to high multi-directional movement requirements, plus they required a minimum 120-minute EI Fire Rating to protect the future residents. To add to the complexity, there were shear connectors within the floor slabs that also needed protection to ensure their structural integrity in the event of a fire.An “E120” denotes that the system will not allow flames and hot gases from physically passing through the element for 120 minutes, which also explicitly denotes that the system will achieve 120 minutes ‘Integrity’ (E) and ‘Insulation (I), known as EI120, which therefore also achieves 120 minutes ‘Stability’ (R) in fire.Emshield-DFR-2 provided the ideal solution, and one which could also be rapidly installed from below in a single operation. This specialist work was completed by specialist fireproofing contractors, Gould Sealants Limited, working for Main Contractor, Morris Roe. Emshield-DFR/WFR is an EN-1366-4 tested, fire-rated movement joint, designed to be used in movement joints in exterior and interior walls where a combination of watertightness, fire-rating, sound attenuation, and thermal-efficiency are required. Key performance parameters include:-       Up to 100% joint movement (+/- 50% capability);-       100% watertight joints; -       No mechanical fixings to the structure;-       Accommodate changes in direction between the horizontal and vertical plane;-       Accommodates 3-Dimensional movements (including in shear & vertical, as well as joint expansion and contraction;)-       no additional sound concrete cut-outs required;-       Up to 4-hour fire integrity rating to EN1366-4; -       Up to 4-hour thermal Insulation rating to EN1366-4;-       High acoustic insulation & barrier performance; -       CE Approved and MarkedFor more information:Contact: David Mackay Tel: 01257 266696NCC Movement Joints Limited

F. Ball and Co. Ltd.’s newest high-performance water-mix smoothing underlayment, Stopgap 1500 AquaPro, and Styccobond F48 PLUS temperature tolerant fibre-reinforced adhesive have enabled a fast-track LVT installation as part of barn conversions to create three holiday cottages in rural Nottinghamshire.Flooring contractors installed floorcoverings in bedrooms, open-plan living and dining areas and corridors of three previously disused farm buildings of varying size, a total area of over 200m2.Work began by sanding down the new concrete bases, which had been installed as part of the renovation of the properties, by mechanically preparing them, removing any laitance, contamination, dust and debris, to leave a solid, sound, micro textured surface to receive floor preparation products.A moisture test was undertaken by one of F. Ball’s technical representatives to ensure that the building’s subfloors were dry enough to receive floorcoverings. Surfaces were then primed using Stopgap P131 general-purpose primer to promote the application characteristics of subsequently applied subfloor preparation products.Stopgap 1500 AquaPro was applied to create a perfectly smooth base for floorcoverings. Fast-setting and fast-drying, it is walk-on hard in as little as 60 minutes after application and ready to receive floorcoverings from just four hours. The product uses the latest technology to offer a water-mix smoothing underlayment that can be applied over old adhesive residues, including bitumen, carpet tile tackifiers and ceramic tile adhesives. As it is moisture resistant, it can be applied to damp subfloors prior to the application of a waterproof surface membrane.Flooring contractors then used Styccobond F48 PLUS to adhere 7-inch wood-effect vinyl planks in each of the three cottages. The temperature tolerant adhesive holds floorcoverings in place when subject to high temperatures, which may be an issue as a result of solar gain caused by large patio doors. This can cause tenting and gapping at the edges of vinyl floorcoverings as a result of repeated expansion and contraction over time. Fibres in the adhesive also provide high initial grab, a benefit when installing LVTs.Commenting on the project, Anthony Holmewood, fitter at Forester Flooring, said: “Using Stopgap 1500 AquaPro meant that we could complete the work in less than a week. We opted for Styccobond F48 PLUS to install LVTs mainly because we like the adhesive, but also for the reason that floorcoverings are exposed to direct sunlight in some areas.”

County Sligo has been blessed with a brand-new luxury hotel, the internationally renowned Radisson SAS Hotel, where the comfort of guests and staff is of paramount importance. Every precaution has also been taken to ensure the safety of residents including the installation of high quality, clear view fire-resistant glass products, Pilkington Pyrostop® and Pilkington Pyrodur®, which have been fitted extensively throughout the entire hotel.Pilkington Pyrodur® is a laminated glass with a special interlayer, developed for the optimum combination of minimum thickness, integrity fire resistance and impact performance. In a fire, the glass forms an opaque barrier to exclude flames and hot gases as well as blocking the sight of the fire, hence reducing panic. In addition to its integrity performance Pilkington Pyrodur® reduces the transfer of radiant heat significantly.Jackie Corcorran of main contractor, J J Rhatigan & Co. Galway was closely involved in the specification of the specialised glass alongside White Bros. Joinery Sligo & Jim Walsh of Greaney Glass Galway. 160 m2 of 10 mm Pilkington Pyrodur® with a 30-minute integrity rating was installed within the corridors of the building. In other areas where there is a slightly greater risk of fire, such as the kitchen area, internal doors and function room screens, were fitted with 21 mm Pilkington Pyrostop®, which provides 60 minutes fire integrity and insulation.Specialist glass & glazing contractors, Greaney Glass, were responsible for installing the fire-resistant glass and Ivan Greaney, Managing Director, comments: “For such a prestigious project it was imperative we used a fire-resistant glass we could trust. There could be hundreds of people within the hotel at any one time so we needed to use materials that would provide maximum protection under the most extreme circumstances. As Pilkington Pyrostop® and Pilkington Pyrodur® are backed by a full suite of impact and fire performance tests, we had no doubts that this was the ideal glass for this project.”Pilkington Pyrostop® and Pilkington Pyrodur® provide excellent levels of protection and have been tested and assessed to BS and EN standards. Not only do they offer excellent fire-resistance they also fully comply with impact safety tests and permit safe breakage in the manner of a laminated glass. In addition, they provide acoustic improvement over standard fire-resistant glass, an important consideration in the hotel that offers a peaceful and relaxing retreat for guests.

VIEGA MEGAPRESS – THE IDEAL FIT FOR FESTOOL HQAward-winning international power tools manufacturer, Festool has invested £10 million into its new headquarters based in Bury St. Edmonds. As part of the construction, Viega’s Megapress press connection technology has been utilised for the building’s new state-of-the-art heating system, allowing for an efficient and effective installation.Festool has relocated its 55 office-based employees to the new site in Suffolk Business Park, in Bury St. Edmonds. The large, modern facility includes meeting rooms, cafés and office space with a separate warehouse and demonstration facility. It was important for the company that its new headquarters represented a modern and sustainable design and could be a facility where the company can continue to expand and develop.The headquarters has a complex range of HVAC systems, including a hybrid air conditioning system, underfloor heating and domestic services. Viega’s carbon steel press fitting system, Megapress was an ideal solution to create the pipework connections, offering a fast and effective alternative to traditional methods such as welding.David Aldous, Mechanical Project Manager at Ceetech, the contractor for the project, commented: “We selected Megapress as it ticked all the boxes. It provided a secure press connection without the need for welding and allowed our team to undertake the work efficiently and effectively. This project had to be completed to a tight deadline, so it was essential to make strategic time gains throughout the installation period.“We were also able to make valuable time-savings because with the Megapress system, there is no need to prepare the pipe surface or clean it after as with welding, threading or grooving. From a health and safety perspective – it also removes the element of hot works.”A highly effective pressing method, Megapress connections can be made in just seven seconds – helping to achieve a 60% reduction in installation time. After cutting the pipe to the required length, contractors need only deburr the cut surface, slide the press fitting into place and press the connection.The simplicity of the press fitting process also ensures that a uniform seal is created on each connection throughout the project; particularly important on large-scale developments where there is set to be thousands of joints across a single site. Once the fitting has been pressed, it forms a strong and secure connection.David concluded: “The Megapress system is excellent, I’ll certainly select Viega again for future projects. It was a clean installation and the end-client was pleased with the high quality of work."

The creation of an ultra-modern Teaching Building as a new core to a long established school in Oxfordshire, has included the installation of custom designed and manufactured stainless steel sinks, worktops and splashbacks and other units from GEC Anderson for several of the different technical spaces.The Tudor Hall School, originally founded in 1850 by the Rev TW and Mrs Todd at a site in Salisbury, has been at its present location at Wykham Park in Banbury since World War II, while the past decade has seen some £15 million invested in ensuring the Independent Girls Boarding and Day School offers the best possible facilities.The Birmingham office of ADP Architects has been responsible for the design work on this latest project, while Clegg Construction Ltd of Nottingham was the main contractor carrying out the work. Acting as a specialist sub-contractor, GEC Anderson conducted site visits and liaised with the project team in order to ensure its custom fabrications met the schools’ health & safety as well as technical and teaching requirements. The manufacturer also worked closely with Tudor Hall’s Bursar, Neil Farquhar to ensure its site installation visits in no way interfered with the academic activities as lessons continued throughout normal term time. One of the architects involved with the project from early on commented: “The GEC Anderson sinks, work-surfaces and other fabrications were specified for the Food Technology Area as well as units for the Ceramics and Textiles rooms. The new centre opened on schedule last Easter in time for the start of the 2018 summer term and everyone involved has been pleased with the results.”A spokesperson for Tudor Hall added: “The new Teaching Centre is the largest and most ambitious addition to Tudor Hall facilities to date and sits at the heart of the school site. Designed to provide teaching spaces for the core subjects of Mathematics and English and specialist classrooms for the creative arts, the Teaching Centre transforms the teaching provision which Tudor Hall offers and we are delighted to have it operative, and we are already witnessing its impact.” Since its formation in 1962, GEC Anderson has built its reputation for the supply of top end stainless steel sinks and sanitaryware on a combination of innovative design, top quality materials and expert craftsmanship. In addition to the company’s Decimetric system of cabinets, sinks, drainers and other equipment - widely specified for sectors including health and catering – it is able to create custom engineered solutions to exactly fit any space or specification.

Recticel Insulation’s innovative insulation board - Eurowall +, which has a tongue and groove joints on all four sides to ensure an airtight fit and improved thermal performance, was selected for a desirable new housing scheme built beside one of England’s eminent waterways.The Magenta Court development in Apsley, Hemel Hempstead is a multi-award nominated social housing project on behalf of Dacorum Borough Council. The £6.5m scheme, which stands alongside the famous Grand Union Canal, comprises 29 one-and-two bedroom flats within four blocks. The buildings’ design was inspired by the surrounding wharf architecture present in a nearby listed cottage, papermill and Apsley Lock.Being delivered by main contractor Jarvis Contracting, working with architects RG+P, key to the programme’s success was achieving an energy-efficient building fabric. This led to the specification of Eurowall®+, a high-performance PIR solution from Recticel.This flagship product helps to achieve a 0.18 U-value with a 90mm-thick panel in a 100mm cavity. The lightweight, easy-to-handle board features a tongue-and-groove joint on its four sides, allowing it to be used as full-fill cavity wall insulation with a 10mm clear cavity. The additional space makes for a rapid, more convenient fit for bricklayers when it comes to installation.Simon Blackham, Technical Manager at Recticel explained:This was a tremendous project to be involved with. It’s a superb housing scheme in a great location. With the buildings’ overall thermal efficiency among the priorities, it’s the type of project Eurowall®+ was created for. Further, it enhanced the programme’s sustainable credentials by reducing on-site labour times, thanks to the additional space it affords installers.Eurowall®+ is an exemplar of how high-performance materials can maximise a home’s thermal performance through a fabric-first approach. Its selection for the Magenta Court development was crucial to the creation of a number of desirable, energy-efficient affordable homes, whilst playing a part in ensuring the contractor remained on track to complete the project to the agreed timeframe. About Eurowall®+:Eurowall® + is a premium, high performance full fill insulation board with precision cut tongue and groove joints on all four sides. This ensures that the boards lock tightly together minimising heat loss through thermal bridging. This unique joint offers increased protection against wind driven rain as well as improved windtightness. Eurowall® + is also designed with a 10mm cavity requirement in mind, so that space can be left for conventional bricklaying techniques.

The Oak Cancer Centre at The Royal Marsden’s Sutton site is a state-of-the-art research and treatment facility, designed to bring the hospital’s 400-strong research team and its clinical care facility together under one roof. Specialist brickwork contractors, Lesterose Builders, were appointed by main contractor ISG to design and build the 2,800m2 masonry façade. As a result, they were responsible for ensuring the façade complied with the relevant thermal and fire safety regulations. The time and cost challenge The architect’s specification named a rock mineral wool product, but when Sam O’Keefe, Commercial Manager at Lesterose Builders, tried to place the order, there were two problems. He explained: “The first issue was availability – there was an eight to ten week lead time due to materials shortages. And the second issue was cost. We discovered the original insulation manufacturer had two planned price increases, and the extended lead time and phased delivery schedule meant that the Oak Cancer Centre project would be hit by both.” These two issues would not only delay the build, but would push it significantly over budget. So Lesterose Builders needed another insulation solution. Meeting the specification Lesterose Builders turned to Knauf Insulation, a fellow member of the Association of Brickwork Contractors (ABC). Knauf Insulation’s sales team looked at the specification and was able to offer an equivalent – 200mm Rocksilk® RainScreen Slab.  Rocksilk® RainScreen Slab is a rock mineral wool insulation product with a thermal conductivity of just 0.034W/mK, which meant it would meet the U-value of 0.21W/m2K. It is also non-combustible with Euroclass A1 reaction to fire classification, which means it will not contribute to the development or spread of fire should it occur. It is British Board of Agrément (BBA) certified for masonry façades at any height as well as for the broadest range of build-ups of any rainscreen solution on the market. This meant Rocksilk® RainScreen Slab was suitable for use in the Oak Cancer Centre because it complies with building regulations that ban the use of combustible materials in the walls of relevant buildings over 18m tall. In addition to fire safety and thermal performance, Rocksilk® RainScreen Slab offers excellent sound reduction characteristics. Crucially, Knauf Insulation was able to meet both the schedule and cost parameters for the project. “Once we had confirmation that Knauf Insulation could match the specification and deliver to the planned timescales and budget, it was then a case of getting the architect’s approval. This went extremely smoothly. We just made a technical submittal with the datasheets and environmental product declaration (EPD) and Rocksilk® RainScreen Slab was approved for use without any queries.” Ease of installation The seven-full loads of insulation were purchased through Parker Building Supplies. These were delivered to the site in eight phases in line with the schedule of works. The product is designed to be easy to install correctly. Superior robustness and durability mean it can be manoeuvred easily into place. And unlike some competitor products, it can be installed with either face of the slab against the substrate, speeding up installation and preventing incorrect installation. Furthermore, the natural flexibility of rock mineral wool means it adapts to minor imperfections in the substrate, while slabs knit together when tightly butted, eliminating air leakage that could reduce thermal and acoustic performance. Rocksilk® RainScreen Slab is also manufactured with ECOSE® Technology, Knauf Insulation’s unique bio-based binder that contains no added formaldehyde or phenol. It is made from natural raw materials that are rapidly renewable, and is 70% less energy-intensive to manufacture than traditional binders, so it is more environmentally friendly. Products made with ECOSE® Technology generate low levels of dust and VOCs (volatile organic compounds) and have been awarded Eurofins Indoor Air Comfort (Gold) certification. Construction work is known for its challenges, particularly around budgets and schedules – but thanks to Knauf Insulation’s Rocksilk® RainScreen Slab, Lesterose Builders was able to overcome both these issues and meet the required specification factors for the Oak Cancer Centre. 

BackgroundThe BISF (British Iron and Steel Federation) constructed the Newarthill properties in the 1940’s, utilising steel-framed walls that were initially coated in cement render and vertical steel panels.In previous renovations overseen by the Local Authority, the upper level of the building was clad in PVC weatherboard, while the lowest floor had its exterior re-rendered. The building is characterised by its non-traditional construction style.The houses had extremely poor thermal performance and the flats were difficult and expensive to heat, especially with the rising fuel prices and current cost of living crisis, meaning some residents were in a state of fuel poverty.North Lanarkshire Council required an EWI solution that would achieve the following three key objectives:- Improve the thermal performance of the property portfolio- Specify a system that would achieve a U-value of 0.17 W/m²K and would involve as little technical detailing around the property as possible- Ensure the properties had a modern and aesthetically pleasing look as the current exterior was tired and datedUnderstanding and appreciating K System’s expertise in this sector and innate ability to deliver best-in-class refurbishments, North Lanarkshire Council appointed the partnership of K Systems and Ailsa Building Contractors to tackle the low rise refurbishment project.Our ServiceAs the Newarthill development was already occupied, a key element of this project was to deliver the refurbishment with minimal disruption to current residents and / or neighbouring houses.This is one of K Systems strengths, ensuring jobs are delivered in a timely fashion, without delay, without disruption, and with full disclosure of each phase given to residents throughout the project to build rapport, trust, and confidence.On this particular low rise refurbishment, which had limited access points for all traffic in and out surrounding its immediate vicinity, K Systems had to work closely with the contractor, main contractor, and local authority to ensure they were working in harmony to negate any unnecessary commotion.K Systems’ technical team also carried out regular site visits to make sure the system was installed to the highest standard, in line with specification, and to ensure all involved parties were delivering to time and budget.The refurbishment of the properties is a great example of K Systems’ unparalleled ability to deliver constructional excellence that not only meets but exceeds the expectations of its customers.Technical Project DetailsOn initial scope, the K Systems team identified that a major challenge for this project was going to be the technical detailing between the timber frame sheeted ply at the top storey and precast concrete slab at the bottom. Several U-value calculations were completed by the experienced K Systems team to support the Council’s request of minimal detailing around the property and the target U-value.To meet these requirements, the K Systems P EWI system was specified, which utilises phenolic foam insulation boards. This insulation is lightweight and has a high thermal performance, allowing for thinner sections of insulation to achieve optimal thermal efficiency - perfect for this project, achieving the target U-value of 0.17 W/m²K , up from 0.32 W/m²K.It is a suitable solution for buildings that are restricted in expanding their footprint due to pavements or nearby properties, and can be easily installed on masonry structures, as well as non-traditional structures - an ideal solution for the Newarthill properties.Addressing the request for a modernised aesthetic, a dash render finish was specified. This render is extremely robust, hard-wearing, and low maintenance, ensuring the properties’ refreshed exterior would remain for years to come. The dash render was also complementary to the existing local property portfolio which was something the Council wanted to achieve.This refurb completely transformed cold, weathered, distressed housing in a Scotland suburb into warm, comfortable, aesthetically pleasing homes that met the exact requirements of North Lanarkshire Council and reduced the energy bills for residents due to improved thermal performance.
